Overview

Release notes

What's included?

Free trials

Smaller, faster, smarter code

Make sure your code is the best it can be. Our compiler makes it fast, effective and highly compact. And powerful code analysis ensures its quality. The compiler and the debugger of IAR Embedded Workbench are by many considered the best in the industry.

Working with safety-critical applications?

The functional safety versions of IAR Embedded Workbench are certified according to IEC 61508, the international umbrella standard for functional safety, as well as the automotive standard ISO 26262.

Latest benchmarks

We are proud of the benchmarks we get.

Outstanding speed optimizations enable IAR Embedded Workbench to generate very fast performing code. With the shortest possible execution times it is the ultimate choice for developing low-power applications.

EEMBC is a non-profit industry association for embedded microprocessor benchmarks. EEMBC CoreMark is a simple, yet sophisticated, benchmark that is designed specifically to test the functionality of a processor core. Running CoreMark produces a single-number score allowing users to make quick comparisons between processors.

Highlights in latest versions

IAR Embedded Workbench for Arm, V8.22
Released Feb 23

IDE performance improvements

General improvements of the IDE startup time and overall performance. Further performance improvements will be implemented in the next release in Q2 2018.

Improved RTOS awareness plug-in for Amazon FreeRTOS

Now with full control of the execution at the task level and enabling display of the local execution context for each individual task.

CMSIS version 5.3 including CMSIS NN for machine learning

CMSIS version 5.3 adds the CMSIS NN software library, a collection of efficient neural network kernels developed to maximize the performance and minimize the memory footprint of neural networks on Cortex-M processor cores.

ST ST-LINK debug probe TCP support

ST-LINK debug driver support for ST-LINK Shared mode using a TCP server.

Nuvoton Nu-Link debug probe support

Nuvoton Nu-Link debug probe support is now integrated into the IAR Embedded Workbench for Arm installation.

Atollic TrueSTUDIO project converter

A project converter is now available to ease porting Atollic TrueSTUDIO projects to IAR Embedded Workbench for Arm.

IAR Embedded Workbench for MAXQ, V2.43
Released Oct 31

IAR Embedded Workbench for Arm, V.8.20
Released Oct 17

Initial support for the Arm v8-R architecture

This release provides basic supports for the Arm v8-R/Cortex-R52 architecture.

Stack protection

The IAR C/C++ compiler for Arm now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection.

Fault exception viewer

The Fault exception viewer is a new debugger window that provides useful information about the cause of a fault exception. It lists the peripheral registers in the System Control Block (SCB) that control fault exceptions and provide information of their cause. All Cortex-M processors have a fault exception mechanism included and is therefore supported by this new feature.

Updated MISRA C:2004 package in C-STAT

The MISRA C:2004 package in C-STAT has been updated with about 20 new checks, of which some are enabled by default.
